State the service life that the corresponding filter core of the first preset value described in TDS change curve is filter core using duration；When the filter core
Default working index is the waterdrainage amount of unit time when being the second preset value, then the relationship of the flow discharges and discharge time is bent
When flow discharges are less than the second default preset value in line, the service life of the filter core terminates；When the filter core presets work
Making index is the single water time not less than third preset value, then in the water time changing curve processed water time processed be greater than it is described
When third preset value, the service life of the filter core terminates.
For example, for ultrafiltration system, it is desirable that often separate water up to 1.2L.If going out for accumulative discharge time 1 minute of statistics
